Preface
With the development of the front-end field and the need for a social division of labor, after the front-end siege, another important job is born-restructuring the siege! One of the major features of the so-called rebuilding and siege attack is that they are proficient in writing CSS configuration files... Front-end

The alternative to military action was economic action---------Rochambeau lent to Wash
specific way the cluster module implements multiple processes.
Cluster modules to implement multiple processes
Now the cluster can be said to be fully done with load balancing. In cluster I have already made a statement. Let's take a look at the actual implementation.
var cluster = require (' cluster ');
var http = require (' http ');
var Numcpus = require (' OS '). CPUs (). length;
if (cluster.ismaster) {
console.log (' [Master] ' + ' Start master ... ');
for (var i = 0; i

The AB command is very low on the computer that emits the load, does not occupy a high CPU, and does not consume a lot of memory, but it can cause a huge load on the target server, which is similar to the CC attack. The use of their own testing should also be noted, or too much load at a time, may cause the target server due to resource consumption, serious even caused the crash.some articl

IV. Load Testing
Once an application works properly, it is essential to understand how the application runs as a whole, regardless of its components or as a whole.
The load test simulates the behavior of a group of users to determine how the application performs under the load.
Next, we will introduce two testing tools: AB and siege.

1. AB testing tool
As part of the Apache HTTP Server project, AB is a relatively simple benchmark testing tool developed and applicable to most environments where Apache is installed.
It has many parameters, and we have a slight adjustment to how to guide the test. Three of them are frequently used:

The HTTP module is used here. Of course, it can also be replaced with the socket module. However, the cluster and the single side are confused due to this writing. Therefore, we rec
